I have an Amiga 2500 with OS 1.3 that will boot only if the A2630 card is in the machine. I thought that a 2500 was simply a 2000 with the addition of an A2630 (or A2620). The 68000 chip is firmly in place on the motherboard, so I have no idea what is going on here. Could the 68000 or something else on the motherboard be damaged?
A2500 OCS or ECS? Revision of the board & Chipset?
